Mark, in my opinion, there are probably lots of reasons for rudeness, etc from opinions being expressed on this message board. One of course is anonymity-something you would never say face to face to someone, you can post here and no one knows who you are. Changes in manners is another reason-children are not taught manners as children and grow up to be adults with no manners either. Young children who live in our neighborhood call my husband by his given name even though they are 8 & 10 and he is 77 and they have not been taught to say Sir. Another possible reason-certainly not applicable to everyone-is new researchers who have never learned to ask politely-this still goes back to manners. In my former workplace-I am retired now-young folks called everyone by their first names-but myself-being old school-when a customer called, I called them Mr., Mrs. or MS.
